thumble

designer's own words:

this design has been generated by a surface modelled following the palm and thumb shape.
continuity along the front direction has been searched between the axis and the lever using a variable section for the first one that starts from a circle to become a shape that smoothly integrates the lever. a polished highly reflective finishing was chosen to help reading the minimal surface curvatures.
